Music Implementation For Video Games

I was given a Video Game Trailer and a bunch of different kind of Music; I had to choose the song(s) I want and edit them in a way to make the soundtrack for this Video.

I wasn't allowed to use anything else but the songs I was given so in order to add some SFX like shoot and explosions I took some drum hits and other parts of different songs and manipulated them with some Plug-ins. I also use elastic audio in Pro Tools to better match Picture & Sound.
